Vedclass · Answer

(B) The Calvin cycle is present in both $C_{3}$ and $C_{4}$ plants. In $C_{3}$ plants,the Calvin cycle occurs in the mesophyll cells. In $C_{4}$ plants,the Calvin cycle occurs in the bundle sheath cells. Since the Calvin cycle is a fundamental process for carbon fixation in both types of plants,its presence does not differ between them. Other factors like the initial $CO_{2}$ acceptor (RuBP in $C_{3}$,$PEP$ in $C_{4}$),extent of photorespiration (higher in $C_{3}$,negligible in $C_{4}$),enzymes (RuBisCO in $C_{3}$,$PEP$ carboxylase and RuBisCO in $C_{4}$),and leaf anatomy (Kranz anatomy in $C_{4}$) differ significantly.
